I'm working in a project that already have a build process running with maven.
Today the build generates a zip file in a given directory, but I need to add the DATE pattern in the file, something like 200917_projectName.zip
Someone have any clue?
Thanks in advance
Using the build-number-maven-plugin allows you to generate a property that can then be used in the finalName property.
The following configuration sets a timestamp property with the format you required, then modifies the finalName to use that property and result in an artifact with that name being output to the target directory.
Note that this name is ignored when installing/deploying the artifact, otherwise Maven would not be able to reliably locate artifacts.
<build>
<finalName>${buildNumber}_${project.artifactId}</finalName>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>buildnumber-maven-plugin</artifactId>
<version>1.0-beta-3</version>
<executions>
<execution>
<phase>validate</phase>
<goals>
<goal>create</goal>
</goals>
</execution>
</executions>
<configuration>
<format>{0,date,yyyyMM}</format>
<items>
<item>timestamp</item>
</items>
</configuration>
</plugin>
...
</plugins>
...
</build>
The Build Number Maven Plugin is what you're looking for. Check the usage page.

i have a maven project using the maven soapui plugin.
Unfortunately this one in my case need an external jar for jdbc for
some groovy scripts.
And according to their documentation, you have to add a repertory called "ext".
And after a dig in their code, this path is hardcoded in their plugin source.
You cant specify it.
So i have to add it directly to a subdirectory of MyProject :
Myproject/ext/postgresql.X.X.jar
I dont want to commit a jar in my project.
Is there a way to tell to maven to pickup a specific jar& add it to a specific directory ?
Thanks in advance for your answer.
You could use maven-dependency-plugin configured in your pom file to copy the artifact into that location during the generate-resources phase, something like this:
<plugin>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.1</version>
<executions>
<execution>
<id>copy-postgresql-artifact</id>
<phase>generate-resources</phase>
<goals>
<goal>copy</goal>
</goals>
<configuration>
<outputDirectory>${basedir}/ext</outputDirectory>
<!-- if you need to rename the jar -->
<destFileName>postgresql.X.X.jar</destFileName>
<artifactItems>
<artifactItem>
<groupId>postgresql</groupId>
<artifactId>postgresql</artifactId>
<version>X.X</version>
</artifactItem>
</artifactItems>
</configuration>
</execution>
</executions>
</plugin>
When I try to use the plugin "maven-war-plugin", it copies all libraries to / WEB-INF/lib, how to copy to another directory? Example: "/ libtest"
I'm not sure to understand why you need to do this but I see two points here:
Avoiding dependencies to get copied into WEB-INF/lib (if not, then just skip the part related to 1.)
Getting them copied to another directory.
For 1. I'm assuming you need the dependencies (because you want to compile against them) but if you don't want the Maven War Plugin to copy them in WEB-INF/lib, you'll have to play with their scope, for example by declaring them as provided.
For 2. the Maven Dependency Plugin will be helpful here and I think you could use dependency:copy-dependencies, for example during the pre-package phase. Use it like this:
<project>
[...]
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>copy-dependencies</id>
<phase>pre-package</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<!-- configure the plugin here -->
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
[...]
</project>
And configure the outputDirectory (and other parameters you could need).
Use the maven-dependency-plugin.
I would like to place the names of the dependencies in a text file that is distributed inside a package that is built with Maven.
I am planning to use the maven assembly plugin to generate the tarball package, and use filtering to put the names in the text file.
The only problem is, I don't know how to reference the dependencies in the first place.
You don't need to use filtering for that, use the Maven Dependency plugin and its a dependency:tree goal to display the dependency tree for this project. Set an output file with the... outputFile optional parameter. So the configuration might look like:
<project>
...
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>tree</id>
<phase>prepare-package</phase>
<goals>
<goal>tree</goal>
</goals>
<configuration>
<outputFile>${project.build.outputDirectory}/dep.txt</outputFile>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
...
</project>
Running the package phase would generate the dependency tree in target/classes/dep.txt and package it in the artifact. Adapt it to suit your needs.
You can use the maven-dependency-plugin dependency:tree to output the tree of dependencies into a file.
mvn dependency:resolve seems to be what you are looking for. Put following plugin configuration to your POM file:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>list-dependencies</id>
<phase>prepare-package</phase>
<goals>
<goal>resolve</goal>
</goals>
<configuration>
<outputFile>dependencies.txt</outputFile>
</configuration>
</execution>
</executions>
</plugin>
It will produce file dependencies.txt with content similar to:

I have a project (here called my-artifact) which needs to generate sources from a model file. I've created a maven-plugin (my-code-generator) which is used as described in the pom.xml excerpt below. It loads and processes the model.xml from my-artifact's resources and generates code using some predefined templates stored within the plugin. The question is how my-code-generator could access these templates as they are not in the project resources but within its own resources.
Thanks in advance

Just use the ClassLoader, to get resources from the MyCodeGenerator Maven plugin.
Add something like this to your MyCodeGeneratorMojo
URL getTemplate(String fileName) {
return this.getClass().getResource(fileName);
}
Within the MyCodeGenerator Maven plugin, add the template(s) to the src/main/resources directory (don't forget to use the correct package entry (directories) within that directory).
By including them in the jar file for the plugin and referencing them via classpath, via ClassLoader.getResourceAsStream.
By packaging them as another artifact, declaring them as a dependency, and calling the dependency-resolution API, which is a lot more work.
I'm trying to add the svn.revision to project version as a build number and can't seem to do so. My jar has the correct name durin packaging, but its installed in the my local repository it is as if ${buildNumber} is/was undefined when the version was set.
I get foo-1.0.0-SNAPSHOT-${buildNumber} instead of foo-1.0.0-SNAPSHOT-304
Any idea what I'm doing wrong or is adding a revision to the project version a bad idea? Thanks for the help.
<project>
...
<version>1.0.0-${release.identifier}-${buildNumber}</version>
<properties>
<release.identifier>SNAPSHOT</release.identifier>
</properties>
...
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>buildnumber-maven-plugin</artifactId>
<executions>
<execution>
<id>useLastCommittedRevision</id>
<goals>
<goal>create</goal>

<configuration>
<useLastCommittedRevision>true</useLastCommittedRevision>
</configuration>

The problem has two parts:
You're trying to set the buildNumber into the version before it is resolved so it will always be ${buildNumber} rather than the resolved value.
Instead of trying to dynamically change the version, you should set the buildNumber into the finalName element in the build. This will create the artifacts with the intended name in the local repository.
The install plugin will ignore the finalName and deploy it as 1.0.0-SNAPSHOT regardless, I don't know of a way to address that. The buildNumber is added to the Manifest if you configure the plugin as below.
So your configuration would be something like:
<version>1.0.0-${release.identifier}</version>
...
<build>
<finalName>${project.artifactId}-${project.version}-${buildNumber}</finalName>
...
</build>
I would avoid using build numbers on SNAPSHOT projects.
Maven provides the SNAPSHOT keyword to signify a volatile project in active development. So if you reference a project with a SNAPSHOT dependency version, Maven will automatically check for updates and keep your dependencies in sync.
If you then add a build number to the end of that version, you will have to manually update the dependencies, so you lose any benefit of having the SNAPSHOT suffix.
I personally avoid using build numbers where possible anyway. If I have to update a project, I just bump the version number, or use a suffix like beta-2 or RC2. If you need to track the revision in the SNAPSHOT, I'd recommend adding it to the Manifest so you can check where the build originated, but use the standard SNAPSHOT suffix to allow Maven to resolve the versions normally. The configuration below shows how to add the revision to the Manifest.
As far as your configuration is concerned, it looks OK to me assuming your SCM url is set up correctly. If you have no SCM configuration in your POM that may be the problem.
Can you run with -X and check for any output from the plugin indicating why it isn't setting the property?
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>buildnumber-maven-plugin</artifactId>
<version>0.9.4</version>
<executions>
<execution>
<id>useLastCommittedRevision</id>
<phase>validate</phase>
<goals>
<goal>create</goal>
</goals>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.1</version>
<configuration>
<archive>
<manifest>
<addDefaultImplementationEntries>true</addDefaultImplementationEntries>
</manifest>
<manifestEntries>
<Implementation-Build>${buildNumber}</Implementation-Build>
</manifestEntries>
</archive>
</configuration>
</plugin>
Add this after the buildnumber-maven-plugin:
<plugin>
<groupId>io.github.michaldo</groupId>
<artifactId>nashorn-maven-plugin</artifactId>
<version>0.0.1</version>
<executions>
<execution>
<phase>validate</phase>
<goals>
<goal>eval</goal>
</goals>
<configuration>
<script>
$project.artifact.version = "${buildNumber}";
</script>
</configuration>
</execution>
</executions>
</plugin>
And the buildNumber will be recognized by packaging and deploy.
